要旨:
An automatic procedure is presented to generate a multiresolution
head model from sampled surface data. A generic control mesh serves
as the starting point for a fitting algorithm that approximates the
points in an unstructured set of surface samples, e.g.~a point cloud
obtained directly from range scans of an individual. A hierarchical
representation of the model is generated by repeated refinement
using subdivision rules and measuring displacements to the input
data. Key features of our method are the fully automated
construction process, the ability to deal with noisy and incomplete
input data, and no requirement for further processing of the scan
data after registering the range images into a single point cloud.
